For adults and children over the age of 12, staying up to date on COVID-19 vaccination means you need booster shots, according to the U.S. Centers for Disease Control and Prevention’s recommendations. Staying up to date on COVID vaccination is the best way to protect individuals and communities against the virus. Health officials expect cases of COVID-19 to increase in the fall and winter months. There are updated booster doses now available from Moderna and Pfizer that have been updated to target the Omicron variant in circulation now, as well as the original strains that were covered by previous vaccines. These updated “bivalent” vaccines have received emergency use authorization from the U.S. Food and Drug Administration and are available at pharmacies and health care providers. The older boosters are no longer available to individuals aged 12 and older.

Q: When do I need a booster dose?

A: It depends on multiple factors, including your age, if you are moderately or severely immunocompromised, the vaccine you first received and the timing of your last COVID vaccination dose.
  • Use the CDC’s online tool to find out when you need a booster, and which type of booster dose best fits your status.

Q: Who can get an updated booster dose?

A: Individuals ages 12 years and older who have completed a primary series of vaccination (either Pfizer, Moderna, Novavax or Johnson & Johnson), as well as those who have received a previous monovalent booster dose, are eligible for an updated bivalent booster dose. The bivalent Moderna COVID-19 vaccine is authorized for use as a single booster dose in individuals 18 years of age and older. The bivalent Pfizer COVID-19 vaccine is authorized for use as a single booster dose in individuals 12 years of age and older. Patients who received an initial Pfizer vaccine can opt to receive a Moderna bivalent booster, while those who received an initial Moderna vaccine can opt to receive a Pfizer bivalent booster, if they choose. To be eligible for these boosters, you’ll need to have completed your primary vaccination series and be at least two months out from your last dose of any COVID vaccine. Those who have recently been infected with COVID-19 should wait three months after they tested positive to get this updated booster shot.

Q: What do the updated bivalent boosters contain?

A: These updated COVID-19 booster shots contain coding for the spike protein for two different strains of the virus. One is the original strain that was in the original vaccines and the other will target the spike protein of dominant Omicron variants BA.4 and BA.5. This is referred to as “bivalent.”

Q: Does the updated bivalent booster offer better protection than previous boosters?

A: The FDA says the updated booster(s) will continue to provide protection against the original strain, while also providing better protection against the currently circulating strains of omicron BA.4 and BA.5. It is theorized that the updated boosters will induce a broader immune response that is expected to produce better protection against future variants and provide a boost to ensure you have updated immunity.

Q: Can I get an updated COVID-19 bivalent booster and a flu shot at the same time?

A: Yes, it is encouraged that people get their flu vaccine this flu season and that it is safe to get the updated COVID-19 booster and the flu vaccine at the same time. This will ensure that you are protected against both viruses.
